Editing Sigil (computer programming) (section)

===Literal affixes===
While sigils are applied to names (identifiers), similar prefixes and suffixes can be applied to [[Literal (computer programming)|literals]], notably [[integer literal]]s and [[string literal]]s, specifying either how the literal should be evaluated, or what data type it is. For example, <code>0x10ULL</code> evaluates to the value 16 as an unsigned long long integer in C++: the <code>0x</code> prefix indicates hexadecimal, while the suffix <code>ULL</code> indicates unsigned long long. Similarly, prefixes are often used to indicate a [[raw string]], such as <code>r"C:\Windows"</code> in Python, which represents the string with value <code>C:\Windows</code>; as an escaped string this would be written as <code>"C:\\Windows"</code>.

As this affects the semantics (value) of a literal, rather than the syntax or semantics of an identifier (name), this is neither stropping (identifier syntax) nor a sigil (identifier semantics), but it is syntactically similar.
